Installing Memcache on MAMP

For the better part of 2 hours I tried and failed to get the Memcache extension installed on MAMP.  I tried following several guides, but everything fell flat on it’s face about 75% of the way through.  I eventually figured it out, and I wanted to share it so that other people don’t have to go through the pain and suffering that I did.  It turns out to be surprisingly easy, but YMMV.

Step 1: Install XCode

Step 2: Make the MAMP PHP binary files executable

sudo chmod +xrw /Applications/MAMP/bin/php5.3/bin/p*

Step 3: Get the Memcache extension source

cd ~
tar -zxvf memcache-2.2.5.tgz
cd memcache-2.2.5

Step 4: PHPize the Memcache extension files


Step 5: Compile the Memcache extension


Step 6: Add the extension to the PHP.ini file

Add the following to the end of your PHP 5.3 ini file via the MAMP file menu.

Step 7: Copy the memcache extension to the PHP extension folder

cp modules/ /Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-[yourtimestamp]/

The “[yourtimestamp]” varies per installation, but you should just be able to tab complete that part.
